FARM SHOW bought Leafguard gutters for our office building three years ago (www.leafguard.com or 800 532-3482). The one-piece seamless gutters are formed on site. Our old gutters were worn out so we had them ripped off and replaced. Leafguard gutters have performed flawlessly, keeping the gutters clean of the leaves and seeds dropped by several huge silver maples trees that tower over our headquarters. Leaves wash over the top of the gutters and fall to the ground while water follows the curved top, flowing into the gutters. After many years of having to clean out gutters by hand twice a year, we couldn't be more pleased. The cost was about 30% more than conventional gutters. Mark Newhall, Editor & Publisher, FARM SHOW.
